If the number x4461 is divisible by 11, what is the face value of x?

1. Divisibility by 11 uses the alternating sum of digits from the right: 1, 6, 4, 4, x. 2. (1 + 4 + x) - (6 + 4) = (5 + x) - 10 = x - 5. 3. For divisibility, x - 5 must be 0, so x = 5. _Source: RRB Group D CEN-02/2018 PYQ, Q.82._
